应用复合添加剂（魔芋微细精粉∶瓜尔豆胶∶黄原胶为3∶3∶2）和苦荞麦粉预糊化工艺，解决了苦荞麦粉无面筋无法加工挂面的技术难题。

According to the results of experiments, the mechanism was deducted: the pre-gelatinization starch molecular limited the spread of the other starch molecular and decreased the amount of hydrogenous bond, which lowed the strength of rice noodle. However, the curly starch molecular was propitious to improve the maximum strain.

根据实验结果，推断其机理为：预糊化的淀粉分子限制了其它淀粉分子在糊化过程中的伸展，减小了老化时淀粉形成氢键的数量，从而降低了切粉的强度；卷曲的淀粉分子有助于提高切粉的最大应变。

Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.
